Overview

The goal of this clinical trial is to evaluate the effect of the Botanical Extract in improving sleep symptoms of nonrestorative sleep (NRS) in healthy adults. The main question it aims to answer is

• Does the Botanical Extract improve sleep quality and reduce symptoms of nonrestorative sleep (NRS)? Researchers will compare the Botanical Extract to a placebo to see if it works.

Participants will:

• Take one of 3 doses of the Botanical Extract (125 mg/day, 250mg/day ,500mg/day) or a placebo every day for 8 weeks.
• Visit the clinic four times for checkups and tests and receive three follow-up phone calls.
